Definitions

  • the present invention relates generally to pet food products, and more specifically to a low energy-dense product that is nutritionally complete.
  • Weight can be managed by controlling caloric intake and/or giving significant amount exercise to pets.
  • Caloric intake can be controlled by feeding low calorie pet foods or feeding a smaller amount of regular calorie pet food.
  • Low calorie pet foods achieve low energy density by having increased fiber levels and decreased fat levels in the diets, often resulting in a less palatable food.
  • pets consuming this type of food product often produce larger amounts of feces.
  • owners often feel the need to compensate by feeding more treats to the pet. The treats provide additional calories, resulting in continued weight gain.
  • compliance with feeding instructions often results in the loss of body weight, there is a risk of losing lean body mass along with loss of body fat.
  • Another way to reduce the energy density of a food product is to puff the food product to create a less dense food product.
  • Highly expanded puffed human snack foods are known. Such snacks typically have a bulk density of about 48 kg/m 3 (about 3 lb/ft 3 ) to about 64 kg/m 3 (about 4 lb/ft 3 ) ahd usually have a very high starch content, with carbohydrates comprising 70-80% by weight.
  • puffed breakfast cereals have a bulk density of about 48 kg/m 3 (about 3 lb/ft 3 ) to about 225 kg/m 3 (about 14 lb/ft 3 ) and also contain about 70-80% by weight carbohydrates, with an amylose to amylopectin ratio of about 25:75. Because of the high starch content, such compositions are not nutritionally complete.
  • Highly expanded snacks and breakfast cereals having densities of about 48 kg/m 3 are generally made with pure starch or whole grain cereals and are coated with flavorings subsequent to puffing.
  • pure starch can expand up to 500% and whole grains (65-78% starch) can expand up to 400%.
  • Pet food blends (40-50% starch) can expand only about 200-300% and oilseeds (0-10% starch) can expand only 150-200%.
  • Animal meal, a main nutritional ingredient of animal meal, is high in protein and is an ingredient that is negative to expansion. Other nutritional ingredients are also negative or neutral to expansion. Thus, in general, more nutritionally complete mixtures have a lower maximum expansion than mixtures high in starch.
  • compositions that include a higher percentage of protein generally require more extreme extrusion conditions involving greater heat and/or pressure. Such conditions cause some of the starch to degrade. When the starch degrades, the resulting product either fails to puff or collapses upon exiting the extruder.
  • EP 0465364 discloses an antiobesity food having a bulk density in the range from 100-300 kg/m 3 .
  • the antiobesity food comprises a combination of a gelatinised starchy material and a fatty acid.
  • a gelatinised starchy material includes high amylose starch.
  • the food is characterised by the complex that is formed between the starch material and the fatty acid upon eating.
  • the foods of EP0465364 prolong the residents time in the digestive tract, thereby prolonging the feeling of fullness and limiting the subsequent calorific intake of the consumer. However they are not nutritionally complete.
  • EP 0747397 discloses a process for producing amylose resistant granular starch.
  • the product contains a high amylose starch and sugar.
  • the starch components of this product do inherently contain a small amount of protein, the protein is present in an amount which is insufficient to address the complete nutritional requirements of an individual.
  • the food products of EP 0747397 are therefore nutritionally incomplete.
  • GB 0850705 discloses a feed formulation comprising treated soybean hulls having a bulk density of 128 kg/m 3 .
  • the soybean hulls provide a source of expandable carbohydrate that can be used as a base to absorb molasses, for example.
  • the starch components of the soybean hulls must inherently contain a small amount of protein, the amount is insufficient to provide a nutritionally complete food.
  • US 4190679 discloses a textured pet food having a bulk density in the range 18 lb/ft 3 to 25 lb/ft 3 .
  • EP 1226762 discloses the use of a starch phosphate ester in the production of expanded extruded foods such as breakfast cereals and snacks.
  • the starch components of the products prepared inherently contain a small amount of protein: the protein is present in an amount which is insufficient to address the complete nutritional requirements of an individual.
  • a nutritionally complete mixture containing sufficient concentrations of high amylose starch can withstand the more extreme conditions used to extrude nutritionally complete compositions.
  • a nutritionally complete composition can be made less dense by puffing the product as it is extruded.
  • a low energy-dense (puffed) product is provided that is nutritionally complete, palatable and satiates the pet. Additionally, because the pet eats a sufficient volume of food, the owner is more satisfied with the pet's eating behavior and is more likely to comply with feeding instructions. However, since the product is puffed, the animal receives fewer calories per unit volume food and the pet loses weight. Furthermore, since the puffed product can be formulated with a high percentage of calories coming from protein (illustratively at least 40% of metabolizable energy), the product will help obese pets lose body fat while minimizing the risk of losing lean body mass.
  • a nutritionally complete pet food product comprising 40% to 50% by weight of carbohydrate, 25% to 40% by weight of protein and 1% to 25% by weight of fat; comprising 15% to 50% cereal grains, 1% to 30% starch having an amylose to amylopectin ratio of at least 40:60. and 5%, to 30% pregelled starches having at least 2500 glucose units, the food product having a bulk density of less than about 240kg/m 3 (about 15 lb/ft 3 ).
  • the pet food product comprises high amylose corn starch, tapioca, and maltodextrin.
  • a method of making a nutritionally complete low energy-dense pet food product comprises the steps of combining a carbohydrate source, a protein source, vitamins, and minerals to form a mixture, wherein the carbohydrate source comprises a starch having an amylose to amylopectin ratio of at least 40:60, and extruding the mixture to form a product having a bulk density of less than about 240 kg/m 3 (about 15 lb/ft 3 ); optionally wherein the carbohydrate source also comprises a starch having an amylose to amylopectin ratio of at least 40:60.
  • Fig. 1 shows the results of a dog palatability study of a puffed product of the present disclosure verses two popular brands of regular dry pet food.
  • a puffed product that has a reduced number of calories per unit volume of food.
  • the puffed product may be used as a weight management food for pets, either as the standard food or as a low calorie snack.
  • the puffed product is palatable, has a low bulk energy density, and can induce rapid satiety. With the puffed product, pet owners can easily restrict caloric intake without limiting the volume of food given to pets.
  • the puffed product is given as a stand-alone food.
  • the puffed product is mixed with standard pet food.
  • Standard pet foods have a bulk density in the range of about 260-440 kg/m 3 (about 16-28 lbs/ft 3 ).
  • the puffed product achieves its low energy density by using a composition including a high amylose starch.
  • the protein content may be raised and the puffed product retains its shape without collapsing significantly upon exiting the extruder die.
  • the resulting puffed product illustratively has sufficient protein content to render the product nutritionally complete by acceptable standards, and has a bulk density about 240 kg/m 3 (about 15 lb/ft 3 ) or less; for example about 64 kg/m 3 (about 4 lb/ft 3 ) to about 240 kg/m 3 (about 15 lb/ft 3 ), and, in some embodiments, the pieces have a bulk density of about 64 kg/m 3 (about 4 lb/ft 3 ) to about 192 kg/m 3 (about 12 lb/ft 3 ), about 96 kg/m 3 (about 6 lb/ft 3 ) to about 175 kg/m 3 (about 11 lb/ft 3 ), or about 144-192 kg/m 3 (about 9-12 lb/ft 3 ).
  • the puffed product may have a crunchy texture, similar to some human puffed foods. Because the puffed product achieves its low bulk energy density by puffing, rather than by increasing fiber levels, protein levels may remain high, and a nutritionally complete food (meeting AAFCO or Food and Nutrition Board Recommended Dietary Allowance (RDA) requirements) may be achieved.
  • AAFCO Food and Nutrition Board Recommended Dietary Allowance
  • Behavior data with a puffed product of the present disclosure shows that pets chew the puffed product longer than a comparable standard pet food, and the residence time for this product in the mouth is longer than the standard product. Therefore, the puffed products of the present disclosure are well suited to deliver chemical agents (e.g. TSPP etc.) that provide dental health benefits. Longer chewing may provide other health benefits as well, such as inducing a flatter glycemic response and increased secretion of enzymes.
  • chemical agents e.g. TSPP etc.
  • the puffed products of the present invention are also suitable for diabetes management.
  • the puffed product is digested and absorbed at a slower rate than the standard product in the gastrointestinal tract. Therefore, it is expected that the glucose and insulin response will be flatter after consumption of puffed product. This is highly desirable for diabetes management.
  • the puffed product can be used to address all three issues simultaneously.
  • the puffed products of the present disclosure can induce satiety more rapidly than with standard pet food. While the exact mechanisms are not fully understood, it is believed that the puffed product induces satiety by three possible mechanisms:
  • the puffed product soaks easily in water, milk, or other liquid to produce a porridge. Because the puffed product is nutritionally complete, embodiments of the puffed product are well suited for use as a weaning food.
  • the dried pet product is produced primarily from a carbohydrate source and a protein source. Other ingredients, illustratively vitamins, minerals, and fats, are added to produce a nutritionally complete food.
  • the puffed dried pet food has a reduced bulk density as compared to standard pet foods, illustratively 4-15 lbs/ft 3 (64-240 kg/m 3 ). Because of the lower bulk density, a pet owner can restrict the pet's caloric intake without reducing the volume of food given to the pet.
  • the carbohydrate source may include grains such as corn, rice, wheat, barley, oats, or soy, and mixtures of these grains.
  • the grain is conveniently provided in the form of a flour or meal. Pure or substantially pure starches may also be used if desired.
  • the carbohydrate source may contain other components, such as protein.
  • the exact carbohydrate source or sources used is not critical. However, it has been found that a carbohydrate source having a high amylose content results in a puffed product that does not collapse significantly upon exiting the extruder dye.
  • a high amylose content starch has an amylose to amylopectin ratio of at least 40:60, and more preferably about 50:50.
  • long chain amylose is at least 2500 glucose units, illustratively 2500-3500 glucose units.
  • the long chain amylose illustratively can be tapioca.
  • the dried pet food illustratively contains about 40% to about 50% by weight of carbohydrate and the carbohydrate contains about 10-15% amylose. It has been found that in certain embodiments maltodextrin also aids in the extrusion process.
  • the protein source may be a vegetable protein source, an animal protein source, or a mixture of these protein sources.
  • Suitable vegetable protein sources include gluten, wheat protein, soy protein, rice protein, corn protein, and the like. These proteins may be provided in the form of flours, concentrates, and isolates as desired.
  • Suitable animal protein sources are muscular or skeletal meat of mammals, poultry, and fish; meals such as meat meal, bone meal, fish meal, and poultry meal; by-products such as hearts, liver, kidneys, tongue and the like; and milk proteins.
  • the protein source is a mixture of rendered animal and vegetable meals.
  • the dried pet food conveniently contains about 25% to about 35% by weight of protein.
  • Illustrative food products may comprise 15 to 50% cereal grains, 1 to 30% high amylose cereal starch, 5 to 30% pregelled starches having long chain amylose (illustratively tapioca), and 25 to 40% protein (illustratively vegetable or animal protein meals).
  • a fat may be sprayed on as a coating.
  • the fat may comprise 1-25% of the weight of the puffed base.
  • tallow equaling 5-15% of the weight of the puffed base may be used.
  • the functional ingredients may include a vitamin, a mineral, conjugated linoleic acid, an antioxidant, a microorganism, illustratively a probiotic, a moiety such as a metabolite or a supernatant of culture of such microorganism, an extract from a plant that may contain any of the above, a dietary supplement, or combinations and mixtures of the above.
  • the functional ingredient, or mixture thereof is selected for its properties in a weight management diet.
  • abrasive agents may also be included. Suitable abrasive agents include ground oyster shells, titanium dioxide, and the like. Similarly, dental care agents may also be included if desired; for example pyrophosphate salts such as tetrasodium pyrophosphate may be included.
  • a dry feed mixture is prepared from a protein source, a carbohydrate source, vitamins, and minerals.
  • the dry feed mixture is then fed into a preconditioner.
  • water or steam, or both is mixed into the dry feed mixture.
  • liquid flavor components such as flavor digests or tallow, may be mixed into the dry feed mix in the preconditioner.
  • Sufficient water, steam, or liquid flavor components is mixed into the feed mixture to raise the moisture content of the dry feed mixture to about 10% to about 20% by weight.
  • the temperature of the dry feed mixture may be raised in the preconditioner to about 65°C to about 95°C.

  • the gauge pressure in the forming zone is about 2000 kPa to about 7000 kPa as desired. If desired, water or steam, or both, may be introduced into the cooking zone.
  • the starch ingredients of the moistened feed are further gelatinized to provide a gelatinized matrix of starch, protein, and other nutritional components.
  • the gelatinized matrix leaving the extruder is forced through a die.
  • Suitable dies may be obtained from Winger Manufacturing (Sebetha, KS). These dies are treated to an RA (roughness average as measured by prophelometer) of less than 30 microninch.
